RBI Monetary Policy — Advanced Topics
Inflation-Growth Trade-off
Phillips Curve
Traditional economic theory: inverse relationship between inflation and unemployment.
•Low unemployment → high employment → higher wages → more spending → inflation
•High unemployment → slack demand → falling prices
In India: Relationship is weak. India often faces "stagflation-like" conditions: high food/fuel inflation with slow growth. Supply-side shocks (monsoon failure, oil price rise) cause inflation without corresponding demand.
Output Gap
•Positive output gap: Actual GDP > Potential GDP → economy running hot → inflationary pressure → RBI raises rates
•Negative output gap: Actual GDP < Potential GDP → spare capacity → deflationary risk → RBI cuts rates
•Estimating potential GDP is difficult — creates uncertainty in monetary policy
Types of Inflation
| Type | Cause | RBI Response |
|---|
|------|-------|-------------|
| Demand-pull | Excess demand over supply | Raise rates, reduce money supply |
|---|---|---|
| Cost-push | Rising input costs (oil, wages) | Limited; higher rates hurt growth without fixing supply |
| Structural | Supply-side bottlenecks (agriculture) | Beyond monetary policy; needs reforms |
| Imported | Currency depreciation or global price rise | Forex intervention + rate consideration |
| Core | Demand-side, underlying | Key focus for monetary policy |
Exchange Rate and Monetary Policy
Balance of Payments (BoP)
BoP = Current Account + Capital Account + Financial Account
Current Account: Trade in goods + services + income + transfers
•CAD (Current Account Deficit): Imports > Exports — India typically has CAD
•Financed by capital inflows (FDI, FPI, ECB)
Capital Account: Cross-border capital transfers
Financial Account: FDI, FPI, external commercial borrowings
Rupee-Inflation Link
•Rupee depreciation → imports become expensive → imported inflation → RBI may raise rates to defend rupee
•RBI forex intervention: Sells USD to support rupee (reduces forex reserves)
•India's forex reserves: $600+ billion (as of 2024) — provides import cover of ~10 months
Global Context — Spillover Effects
US Federal Reserve Impact
When Fed raises rates:
1.US yields become attractive → capital flows from EM (emerging markets) like India to US
2.FPIs sell Indian bonds/equities → rupee depreciates
3.RBI faces pressure to also raise rates to prevent capital outflow
4.Creates conflict with domestic growth objective
Import of Inflation
India imports ~85% of crude oil needs. Oil price rise directly increases:
•Fuel inflation
•Transport costs → food inflation
•Production costs → manufactured goods inflation
